The frequency of ABO , Rhesus(D) and kidd (Jka&Jkb) Blood Group Antigens & phenotypes among Al Halfaween Sudanese tribe

Abstract

This prospective and describtive cross- sectional study, aimed to determine the frequency of ABO, Rh(D) and kell antigens, and phenotypes, among Al halfaween Sudanese tribe. Also aimed at established ABO, Rh(D) and Kidd blood group baseline data for this Sudanese tribe to determine the interaction between this tribe and other Sudanese tribes which will be useful in the blood transfusion. The study was conducted during three months (April to July, 2007), Following informed consent, a total of hundred venous blood samples were collected from unrelated individual into 2.5 ml EDTA containers. All samples were tested for ABO and Rh(D) antigenes by using the slide agglutination techniques, and kidd antigenes were tested by the immune-diffusion gel technique. The results obtained showed that, The O group was most common frequently occurred ( 45% ) , followed by group A ( 31%), group B was found ( 21% ) and least common was group AB ( 3%). The Rh(D) antigen was (87%). JKa was(70%) and JKb was (10%). There was a marked similarities between the Sudanese tribes that lived in the same geographical area this could be due to intermarriage , while the difference that seen in some tribes could be most probably due to the wandering nature of these tribes.
